AB  - Photocatalytic processes have been recognized as promising and sustainable methods for pollutant degradation and energy conversion. Due to the simplicity of the process, capacity for using renewable and pollution-free solar energy, mild reaction conditions, reasonable reaction time, complete pollutant degradation, no harmful byproducts, and cost-effectiveness, photocatalytic degradation processes are more promising than conventional physical methods. Due to its favorable properties, TiO2 semiconductor has been used as an ideal candidate for photocatalytic reactions. However, large band gap, fast e-/h+ recombination, and low light harvesting efficiency are the main obstacles that restrict its practical application. Using  g-C3N4 semiconductor in combination with TiO2  is an excellent strategy to enhance the photocatalytic activity under visible light irradiation. In this study, g-C3N4/TiO2photocatalyst was successfully synthesized and used in single and simultaneous photodegradation of cationic Methylene Blue and anionic Orange G dyes. To examine the heterojunction between g-C3N4 and TiO2 and the mechanism of the transport pathway of photogenerated e-/h+, the photoluminescence spectra and radical scavenger study were applied. The present research offers a novel approach in reaction mechanism analysis for degradation of dye pollutants in single/mixed solutions and suggests a strategy for determination of heterojunction type in g-C3N4/TiO2 systems.

AB  - The visible-light-active heterojunctions based on TiO2 were extensively investigated due to their wide range of energy and environment applications. In this study, g-C3N4/titanate heterojunction photocatalyst was successfully prepared by a simple one-step calcination route from melamine and hydrothermally prepared titanates. The photocatalyst was characterized by different physicochemical methods, e.g., X-ray diffraction (XRD), scanning electron microscopy (SEM), and N2 physisorption analysis. The photocatalytic efficiency of synthesized photocatalyst was evaluated by single and simultaneous degradation of methylene blue (MB) and orange G (OG) dyes under solar and visible light irradiation. The photocatalyst exhibited improved visible light activity due to the efficient separation of photogenerated charge carriers and enhanced visible light absorption. The degradation of MB was examined under different reaction conditions to assess the influence of initial MB concentration, catalyst loading, and pH on the degradation kinetics. Dye degradation study in the single and binary dye systems revealed that adsorption was limiting step that governs the pollutant degradation order. Radical trapping experiments were performed using different types of scavengers to highlight the difference in photochemical reactions and mechanism of MB and OG dye degradation under different light irradiation. Comparison of the reaction pathways under visible and solar light irradiation supported with determined bandgap edges and photoluminescence (PL) analysis suggested that the g-C3N4/titanate heterojunction belonged to the type II heterojunction.

AB  - Textile industry wastewater represents a serious environmental problem because it contains different dyes and toxic substances used during the production and dyeing of textile. Thus, it is necessary to investigate the removal of dyes from wastewater using a simple method such as sorption. Since different salts are used during the dyeing of textile, anions and cations are present in wastewaters and they can affect the process of dye removal. In this paper, the influence of several anions on the removal of textile dyes was investigated. Chitosan and methacrylic acid-based hydrogels obtained by free-radical polymerization and cross-linked with N,N'-methylenebisacrylamide were used as sorbents. Removal of two textile dyes was investigated (anionic dye C.I. Acid Orange 7 and cationic dye C.I. Basic Red 1) at two different temperatures (25 and 50 ° C). The influence of anions on the removal was evaluated using sodium compounds dissolved in dye solutions (NaCl, CH3COONa, Na2CO3, Na2HPO4, NaH2PO4, NaNO3, NaOH). It has been found that hydrogel degree of swelling increased significantly with the increase of pH of the dye solution. The presence of different ions affected the sorption capacity of hydrogels and the best results were obtained when NaH2PO4 and NaNO3 were present.
AB  - Otpadne vode tekstilne industrije predstavljaju ozbiljan ekološki problem, jer u sebi sadrže različite boje i toksične supstance koje se upotrebljavaju tokom proizvodnje i bojenja tekstila. Stoga, potrebno je da se ispita mogućnost uklanjanja boja iz otpadnih voda tekstilne industrije jednostavnom metodom sorpcije. Kako se u procesu bojenja tekstila koriste različite soli, u ovim otpadnim vodama često su prisutni anjoni i katjoni koji mogu da utiču na sam proces uklanjanja boja. U ovom radu analiziran je uticaj nekoliko anjona na uklanjanje boja za tekstil pomoću hidrogelova na bazi hitozana. Korišćeni hidrogelovi su kopolimeri hitozana i metakrilne kiseline dobijeni slobodno-radikalskom polimerizacijom, a kao umreživač je upotrebljen N,N’-metilenbisakrilamid. Anjonska boja C.I. Acid Orange 7 i katjonska boja C.I. Basic Red 1 su korišćene u model vodama, a uklanjanje boja je izvedeno na dve različite temperature (25 i 50 C). Uticaj anjona je ispitan dodatkom natrijumovih jedinjenja u rastvore boja (NaCl, CH3COONa, Na2CO3, Na2HPO4, NaH2PO4, NaNO3, NaOH). Utvrđeno je da hidrogelovi izrazito bubre sa povećanjem pH rastvora. Prisustvo različitih jona utiče na kapacitet sorpcije, a najbolji rezultati su dobijeni kada su u rastvoru prisutne soli NaH2PO4 i NaNO3.
